com.yahoo.searchlib.aggregation.RawData

All Implemented Interfaces:

Cloneable, Comparable<RawData>

public class RawData
extends Object
implements Cloneable, Comparable<RawData>

Constructor Detail

RawData

public RawData()

Constructs an empty data object.

RawData

public RawData(byte[] data)

Constructs a raw data object that holds the given byte array.

Parameters:

data - The rank to set.

Method Detail

serialize

public void serialize(com.yahoo.vespa.objects.Serializer buf)

Serializes the content of this data into the given byte buffer.

Parameters:

buf - The buffer to serialize to.

deserialize

public void deserialize(com.yahoo.vespa.objects.Deserializer buf)

Deserializes the content for this data from the given byte buffer.

Parameters:

buf - The buffer to deserialize from.

getData

public byte[] getData()

Returns the byte array that constitutes this data.

Returns:

The byte array.

setData

public RawData setData(byte[] data)

Sets the byte array that constitutes this data. This does not copy the given array, it simply assigns it to this.

Parameters:

data - The data to set.

Returns:

This, to allow chaining.

compareTo

public int compareTo(RawData rhs)

Specified by:

compareTo in interface Comparable<RawData>

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object

clone

public Object clone()

Overrides:

clone in class Object

compare

public static int compare(byte[] lhs,
                          byte[] rhs)

Implements comparison of two byte arrays.

Parameters:

lhs - The left-hand-side of the comparison.

rhs - The right-hand-side of the comparison.

Returns:

The result of comparing the two byte arrays.
